STATES PATE OFI RICHARD REED HOL, OF PALO ALTO, CALIFORNIA, ASSIGNOR T0 OLIVER OIL- GAS BURNER 0F DRAW Application led April a,

To'alZ whom t may omwem Be it known that I, RICHARD REED MoR- RILL, a citizen of the United States, residing at Palo Alto, county of Santa Clara, State of California, have invented acertain new and useful Improvement in Oil Burners, of which th\e followin is a full, clear, and eXact description, suc as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this application.

`This invention relates to new and useful improvements in oil burners; and the ob- 'ects of the invention are to provide an oil urner which can be easily installed, is of durable construction and which4 will ei'- ciently burn oil without the formation or deposltion of carbon in the yburner tubes or in the connections leading thereto.

Other objects of the'invention are to provide a burner detachably unounted in a suitable housing, and means for regulating the ingress of air to the burner and to the drier desired to be heated by the burner, and to generally improve uponand simplify the construction of oil burners of the class described.

With these and other objects in view. myv

invention consi-sts in certain novel features of construction and arrangements of parts hereinaterdescribed and claimed, and illus trated in the accompanying drawings, in Whichz- Figure 1 is a front elevation of the oil burner partly in section.

Figure 2 is a horizontal cross section taken on line 2 2 of Figure 1.

Figure 3 is a vertical cross section through the burner.

Figure 4 is a horizontal cross section through the vaporizer and the burner and showing means for closing thev open ends thereof. s

Figure 5 is a vertical cross section through a modiied form of the oil burner.

Figure 6 is a front elevation of same.

Referring by numerals to the accompanying drawings, 10 designates a box-like housing open at both ends to form a combustion chamber 11. The rear end of housing 10 is provided with a laterally projecting flange l2 which is designed to be placed against OIL BURNER.

1922. Serial No. 550,821.

the wall of the drier or other apparatus desired to be heated, with the open rear end .AND MACHINE COMPANY, 0F ST. LOUIS, MISSOURI, A CORPOEINTIONv i Vof'charnber 11 communicating with an opening formed in said drier, dotted lines at 14.

The side walls 15 of housing 10 are formed with registering slots 16 which are open at their forward ends for the reception of a casting 17. This casting extends transversely through chambery 11 and its ends rest in slots 16. Casting 17 consists of two preferably tubular members which are parallel with each other. The forward one of these members constitutes a burner 18. The other member which is spaced rearwardly and upward] relative to burner 18, is a vaporizer'19 which is designed to be heated by burner 18, whereby. the oil contained in member 19 is converted into gas.

One end of vaporizer 19 is connected by a pipe 2O to a suitable oil reservoir. and interposed in `this pipe and controlling the flow of oil from the reservoir to the vaporizer is n needle valve 21 manually operable by handle 22 and having a dial 24 by means of which the positioning of the handle 22 can be guided.

The corresponding end of burner 18 is closed by a plug 25 screw-seated therein. The opposite ends of burner 18 andvaporizer 19 are closed by a plate 26 held in posias indicatedin .tion thereon by anut 27 which engages the with the burner.v

In the manufacture of casting 17, a rib 3() iscast integral with the burner and vaporizer, and is then sawed through as indicated at 30a in order to provide for expansion of the metal when the casting is used.

A trough 31 is `formed integral with and extends forwardly'from burner 18 and is designed to receive oil from said burner' through orices 32 formed in the top of the latter. One end of trough 31 is provided with an opening through which access may be gained to the passageway 1T, and this opening is normally closed b v plug 33 screw-seated therein.

An overflow pipe 3l is tapped in the front kwall of said trough near the top thereof and serves to conve)v the excess oil, after it reaches a certain predetermined level in said trough, to an overflow tank. closure plate or deflector 35 is pivotally supported in the side walls 1.3 by means of a rod 36 and is adjustable in position by a handle 3T whereby the size of the opening in the forward end of housing lll may be adjusted to regulate the suppl)y of air to burner 18 and the drier desired to be heated. Plate 35 can be locked in its adjusted position by a screw 38 which is screw-seated in housing 1l). and has its lower end adapted to engage rod 3G.

The top wall of housing lt) is formed with a plurality of inwardly disposed ribs 10 which are embedded in and serve to hold in position a layer of asbestos or analogous material 39 with which the upper portion of the housing 10 is lined.

In the modified form shown in Figures 5 and (i, the housing et() is of cylindrical shape and open at both ends. The oil supply pipe 41 has its end portion 112 bent in the form of a U which is arranged in said housing with its parallel portions occupying a horizontal position. The extreme end of this pipe is closed by a perforated cap L14 which constitutes the burner.

When pipe 41 is in position in housing 40, the burner cap 44 occupies the front end ot said housing below the supply pipe 41 so that the oil contained in the bent portion 42 will be heated and converted into gas by burner 44.

In the operation 0l' my device, the trough 31 is Hooded with oil, which is then ignited, and the heat generated by combustion of the oil heats burner 18 and vaporizer -19 and converts the oil contained therein into gas which will escape under pressure from burner 18 through orices 32. This gas is then ignited and the flames will be deflected inwardly towards the drier end of the housing thereby passing over vaporizer 19, and maintaining it at the proper temperature, so that the oil entering said vaporizer will be vaporized. The air is admitted into chamber 11 through the inlet opening formed in the forward end of said housing and controlled by the closure plate 35 and in passing through said chamber will be heated by burner 18 so that before entering the drier it will be raised to the proper temperature.

That portion o?? rod 28 which is engaged by nut 27, being located exteriorly of casting 17, will not become corroded so that the, peoper working engagement will be maintained hetween it and nut 2l' and no incassi culty will be experienced in removing the plate 26 from its position on the casting 17.

The location of plate or damper 26 in the housing 1l) permits the quantity of air used directly through the burner to be changed without lowering its velocity. By changing the number and size of orifices, the capacity ol the burner is changed as is also the time required for complete combustion. Thus, the suppl)Y of air and oil are properly controlled and the burner is consequently more flexible and ellicient in opertion.

While i have showin and described the prel'erred lorm of my burner, it is obvious that various changes in the size, form and arrangement of parts ot my improved burner can be made and substituted for those herein shown and described without departing from the spirit of my invention.
